No, you should not lubricate spark plugs. Adding lubricants can interfere with the electrical conductivity and lead to misfires. If you're dealing with stuck spark plugs, use a penetrating oil to loosen them before removal. For installation, ensure you're using anti-seize compound sparingly, but avoid direct application on the plug's firing end. Always follow the manufacturer’s guidelines for best results.
